Definitions

  • the present invention relates to a plugging type dental liquid housing container capable of firmly sealing by plugging, hardly causing liquid leakage or the like, and easily opening by only rotating a plugged plug body without soiling a hand.
  • the plug body inserted and fitted into an opening part of the container is used in many cases without using a cap type cover body.
  • the high sealability can be kept by the plug body, there is a problem that it takes time and effort for opening the container.
  • the dental liquid housing container is a small type in general, and thus there is a problem that the handling of opening or the like is difficult. Therefore, when the plug body is used in order to increase the sealability, the handling becomes more difficult. Thus, in the conventional dental liquid housing container, it is remarkably difficult to keep the high sealability together with the easy handling using the plug body.
  • the following opening and closing cap of the container has been used (for example, Japanese Utility Model Laid Open No. 60 -142742 ). It is an opening and closing cap comprising a fitting cylindrical body and a plug body.
  • the fitting cylindrical body is fixed at a pour-out neck part protruded from a barrel part of the container, and the plug body is detachable with the fitting cylindrical body.
  • the fitting cylindrical body comprises a sleeve inserted in the pour-out neck part, and plural of first protruded pieces separately formed on the upper face of an outer circumference of the sleeve.
  • the plug body comprises a top plate having a diameter equal to an outer diameter of the cylindrical body or more, a sleeve provided downward from the lower face of the top plate, a plug core liquid-tightly fitted with the sleeve, and plural second protruded pieces separately formed on the lower face of the top plate at the outer circumference of the plug core.
  • the second protruded piece is run upon the first protruded piece to generate lifting force, and the fitting of an annular projection with a stepped part or a recessed groove is released by the rising force.
  • this opening and closing cap the structure is complicated, and the fitting cylindrical body and the plug body must be inserted into the opening part of the container.
  • this cap can be used to a comparatively large makeup bottle or the like, it cannot be used to the small type dental liquid housing container.
  • the structure as in this opening and closing cap where the plural first protruded pieces and second protruded pieces are separately formed on the lower face of the plug body and the upper face of the fitting cylindrical body respectively and the second protruded piece of the plug body is run upon the first protruded piece of the fitting cylindrical body, to thereby open the cap, is used to the small type dental liquid housing container, the first protruded piece and the second protruded piece cannot be formed largely and the plug body can hardly be lifted to the sufficient height. Thus, contacting length of the fitting cylindrical body and the plug body cannot be sufficiently secured to have high sealability.
  • the following cap structure has been used ( Japanese Utility Model Laid Open No. 3-100141 ). It is a cap structure comprising a cylindrical neck part having upper and lower openings and a cap detachably mounted to the neck part.
  • the cylindrical neck part is provided at an upper end part of the container.
  • an inner circumference part of the neck part has an approximately elliptical shape at an upper portion and is gradually contracted toward the lower portion to have an approximately right circle.
  • the plug body capable of inserting into the neck part is integrally formed downward from a lower face center part, and a base end of the plug body has the approximately same elliptical shape as the upper portion of the neck part.
  • the upper portion of the inner circumference part of the neck part and the base end of the plug body formed downward from the cap are formed to have the elliptical shape.
  • the portions having the elliptical shapes are not engaged each other, to thereby push up the plug body inserted into the neck part.
  • the neck part and the plug body of the cap must be inserted into the opening part of the container and the sufficiently large opening part is needed to make the inner circumference part or the like of the neck part to have an elliptical shape, corresponding to the major axis of the ellipse.
  • this structure can not be used at all to the small type dental liquid housing container.
  • the present invention solves the above-mentioned problems, and the primary objective of the present invention is to provide the plugging type dental liquid housing container capable of firmly sealing by plugging, hardly causing the liquid leakage or the like, and easily opening by only rotating the plugged plug body without soiling a hand.
  • a plugging type dental liquid housing container comprising a container main body having a holding blade plate for holding the container, which is projected on an outer circumference face of a cylindrical liquid housing part having an opening upper end and a closing bottom part, and a plug body having a sealing plug part at a lower end thereof and a contacting blade plate for contacting with an end face of an opening part, which is projected on an outer circumference face of the plug main body starting from the upper end of the sealing plug part.
  • the plug body can be inserted and fitted to the sufficient depth in the container main body to thereby secure high sealability, and the structure is made simple so that the container can be produced easily. Further, by holding only the holding blade plate on the outer circumference face of the container main body and the contacting blade plate on the outer circumference face of the plug body by both hands, and rotating them, the container can be opened easily, and thus the handling is remarkably improved. Further, since the plug body can be rotated with a sufficient force, the plug body can be opened easily even when it is firmly inserted and fitted into the container main body.
